Polk Audio DSW Pro subwoofer speaker amplifier board protection circuit fault repair fix

[@hestingstech]

Howzit I got Polk audio DSW PRO 550wi powers on but no sound will be able to fix it for me?

If you are asking if I can personally fix it for you, i could attempt taking a look to see if there is anything that needs replacing. But you would have to be in the UK, where are you based?

Help, please. I have bought an older Velodyne DD12 and it does not respond to any button I press on the remote control. The remote apparently works because the red led lights up and the infrared sensor blinks when checked with a phone camera. The subwoofer works when connected to a receiver but I can't change any equalization settings or else. What could be the problem and how can I solve it?

[@kaygeebee9155]

Sorry for the late reply, I didn't see this comment being listed earlier. Are you sure it's the right remote control for the unit? If so, it could be the receiving sensor unit on the subwoofer itself, or a loose connection on the inside of the subwoofer. Worth opening the subwoofer up to take a look inside👍🏼

@@kaygeebee9155 Hi there again. Thanks a lot for the response. Indeed, I opened up the sub to take a look and the cable for the IR remote was plugged in on the wrong connector. Who knows who opened up the sub and messed up the cables.. maybe somebody replaced the amp, but now it's working flawlessly. I uploaded a video on my channel on the issue reviewing the sub as well

​@@juanbaclavabah brilliant, well done, great result👍🏼😊🙏🏼

I have a jbl northridge subwoofer, which fails to kick in at low volumes, however it keeps trying to pick up until I raise the volume, any idea about the problem?

[@kaygeebee9155]

Might be an issue with the volume resistor. Try cleaning/refurbing/changing the volume switch to see if that helps the issue 👍🏼

[@smmohy]

@@kaygeebee9155 which volume switch you mean, if that of the subwoofer, it is for the bass and when the subwoofer is working it perfectly controls I think there is something in the relay that puts on the speaker as this is the main problem

[@smmohy]

@@kaygeebee9155 any idea how to check components of my mentioned subwoofer
